Purseweb Spider in Action- Sphodros abbotti

these mygalomorph spiders spend their lives in their tub webs that they build up the sides of trees (cept males during mating season), when prey climbs over their tube they stick their huge fangs through the web to grab the food then pull it through, this was the first time ive seen it in real life , the green moss covered part of the purse was its origional tube that had been attached to a tree, the white lacking moss is construction done in captivity. i believe they come from the SouthEast US
